No matter whether you think about ancient literature and history or read widely modern books and texts, they can't provide a more comprehensive analysis than the treasure of our Chinese culture - the balance of yin and yang. It is the yin and yang reflected in the viscera, qi and blood, the yin and yang of the philosophy of life, and the yin and yang of thousands of phenomena. Masculinity and femininity wax and wane with each other, cause and effect each other, and cannot exist independently. Using the theory of yin and yang balance can not only analyze the past, but also guide the future. Savor the experience carefully, and the positive energy will continue to increase, allowing the two worlds to switch and coexist leisurely, which is the best living and working state.
